I hear actnics are good for the tank. Do the MH produce them or do the MH's make it up in another area? And if not, are they really all that important?

MH bulbs put out a full spectrum of light. Actinics aren't needed, even with 10k MH bulbs. Actinic lighting is "eye candy" in that it will make the corals look more colorful. They won't add anything the MH's don't provide.

Some MH lamps are pretty much blue. I think those up in the 12-14k range and that is almost the same, People add the actinics so that they have the morning and evening look. The actinics are dim looking where as the MH are high power midday light. Its pretty much personal taste.

Ok, as i have had past questions before i now have new ones. There was a big change in plans with my tank. I am not doing the 90g corner tank. I am now doing a 75g or 55g SW tank. So i ask you again. What kind of lighting so i need for the tank. Should i do MH lighting still or T5HO? I still want to keep almost ANY coral i want. I like the SPS and LPS and stuff so i still need good lighting. Same thing with me wanting a anemone. So what should i get?
